Let’s provide a concise overview of ray tracing. We won’t delve into subjects like Monte Carlo and stratified sampling, PBRT, BRDF, rendering equations, denoising techniques, or intricate SDF conce...

Here’s the Chinese version: 这次我是产品经理—用GPT辅助查RTX的bug实例 In this article, I will discuss how I successfully debugged some RTX code using Cursor. Debugging DX12 RTX code can be quite challenging. Wh...

This article is still an informative introduction, presenting a new spherical basis function and its application in lighting description. Recommended prerequisite reading: Introduction to Spherica...

本篇还是比较科普向，介绍了一种新的球面基函数和在光照描述上的应用。前置阅读： 球谐函数介绍（Spherical Harmonics） 大家小学三年级学过概率和统计的话，对正态分布或者高斯分布一定非常了解 [g(x) = \frac{1}{\sigma\sqrt{2\pi}} e^{(\frac{-(x-\mu)^2}{2\sigma^2})}] 拓展到球面也很简单。相比SH的公式...

This article aims to explain Spherical Harmonics in simple terms without using mathematical jargon. It also discusses how SH is applied in Radiometric/Photometric contexts. SH, or Spherical Harmon...

English Version: Introduction to Spherical Harmonics 尽量不用各种术语来讲清楚SH（Spherical Harmonics）系数，以及SH在简单光照描述上的应用。 科普向。 SH，球谐函数，归根到底只是一组基函数，至于这组基函数是怎么来的，不管他。 其实大家小学二年级学过泰勒展开和傅里叶变换的话，对基函数应该是非常了解的。 比如多项...
